-    # Special case pip and setuptools to generate versioned wrappers
-    #
-    # The issue is that some projects (specifically, pip and setuptools) use
-    # code in setup.py to create "versioned" entry points - pip2.7 on Python
-    # 2.7, pip3.3 on Python 3.3, etc. But these entry points are baked into
-    # the wheel metadata at build time, and so if the wheel is installed with
-    # a *different* version of Python the entry points will be wrong. The
-    # correct fix for this is to enhance the metadata to be able to describe
-    # such versioned entry points, but that won't happen till Metadata 2.0 is
-    # available.
-    # In the meantime, projects using versioned entry points will either have
-    # incorrect versioned entry points, or they will not be able to distribute
-    # "universal" wheels (i.e., they will need a wheel per Python version).
-    #
-    # Because setuptools and pip are bundled with _ensurepip and virtualenv,
-    # we need to use universal wheels. So, as a stopgap until Metadata 2.0, we
-    # override the versioned entry points in the wheel and generate the
-    # correct ones. This code is purely a short-term measure until Metadata 2.0
-    # is available.
-    #
-    # To add the level of hack in this section of code, in order to support
-    # ensurepip this code will look for an ``ENSUREPIP_OPTIONS`` environment
-    # variable which will control which version scripts get installed.
-    #
-    # ENSUREPIP_OPTIONS=altinstall
